CHAPTER 2: CELL THEORY Wednesday September 7 Macromolecules: Many of life's molecules are gigantic >Carbohydrates: dietary energy, plant structure >Lipids: long term energy storage (fat) and hormones (steroids) >Proteins: enzymes, structure, storage >Nucleic Acid: information storage Cell Theory: 1. All organisms are composed of one or more cells 2. Cells are the smallest unit of life 3. New cells come from preexisting cells ia cell division (mitosis) Single Celled Organisms: 3.5 Billion Years Old >Prokaryotic: Have single, round DNA ( ucleoid region) >> Archaea: found in extreme conditions (i.e. Thermal vents, Antarctica, ect.) >> Bacteria:
